The majority of prohibited areas are in waters managed by Hydro Tasmania which are legislated in the Marine and Safety (Motor Boats and Licences) By-Laws.

In port areas there are restrictions on operating within the vicinity of certain types of large commercial vessels while they are engaged in port operations. These restrictions are defined by the International Ship and Port Facility Security (ISPS) Code.

Guidelines are  also in place that restricted vessels from operating within the vicinity of Whales and Dolphins

Restricted areas can also be determined for set periods of time, due to marine construction, aquatic events, etc. These are determined through the issuing of a Notice to Mariners.
